A rolling equipment for silica nano aerogel felt
Aerogel felt is a new type of flexible thermal insulation material, which combines nano aerogel with inorganic dimension. Its main performance characteristics are as follows:
1、 Low thermal conductivity
The thermal conductivity of aerogel felt is extremely low, usually between 0.02 and 0.1 W/(m · k), which makes it have excellent thermal insulation performance. Its insulation effect is 2 to 5 times that of traditional insulation materials, effectively reducing heat loss and improving heat source utilization efficiency.
2、 High temperature resistance
Aerial gel felt has high temperature resistance, and its applicable temperature range is generally between -200 ℃ and 1000 ℃ (related to specific products). Some products can withstand high temperatures up to 1100 ℃. In high temperature environment, the performance advantage of aerogel felt is more obvious.
3、 Soft and easy to cut
The aerogel felt is soft, easy to cut and sew, and can meet the insulation requirements of pipes and equipment in different shapes. This greatly reduces the time and labor costs required for installation.
4、 Inorganic fire prevention
The aerogel felt has inorganic fire resistance, and the fire resistance rating usually reaches B1 to A. Its unique three-dimensional network structure avoids the significant decrease in insulation effect caused by sintering deformation, settlement, and other insulation materials during long-term high-temperature use.
5、 Overall hydrophobicity
The aerogel felt has an overall hydrophobic property, which can effectively prevent moisture from entering the pipeline and equipment interior, thus extending the service life of equipment and pipelines.
6、 Green and environmentally friendly
Aerogel felt is a kind of green environmental protection material, which will not pollute the environment during its production and use. At the same time, it can also replace traditional flexible insulation materials such as glass fiber products, asbestos insulation felt, silicate fiber products, which are not environmentally friendly and have poor insulation performance.
7、 Lightweight and high-strength
Aerogel felt is light and has high tensile and compressive strength, which makes it more convenient during transportation and installation, and can ensure the thermal insulation effect.
To sum up, aerogel felt has excellent properties such as low thermal conductivity, high temperature resistance, softness and easy cutting, inorganic fire prevention, overall drainage, green environmental protection, light weight and high strength, and is widely used in industrial pipelines, storage tanks, industrial furnaces, power plants, rescue pods, warship bulkheads, bullet trains, directly buried pipelines, injection molding machines, removable insulation sleeves, heavy oil recovery high-temperature steam pipelines, transportation, household appliances and other fields.
The invention relates to a device for coiling silica aerogel felt material, which has the following structure:;
1. The bracket is assembled by welding iron plates and steel pipes on both sides, with a total of 4 steel rods installed on the lower side, including 1 #, 2 #, 3 #, and 4 #
Driven by chains and sprockets respectively. One of them is equipped with a drive motor, and the other three are synchronously driven.
2. (4 #, 3 #) Two rollers are installed between them, vertically and horizontally, respectively, for fixing the pneumatic expansion shaft in a nu shape. An n-type slot is installed above, consisting of a straight track, slider, and cylinder. Install a U-shaped card slot below, consisting of a straight track, slider, and cylinder.
3. (3 #, 2 #) A cutting component is installed below the two rollers, consisting of a cylinder, a linear track, a slider, and a cutting tool.
4. (2 #, 1 #) A unloading component is installed below the two rollers, consisting of a cylinder, a linear track, a slider, and a rubber roller.
Install the material receiving inflation shaft n-type slot component above, consisting of a cylinder, linear track, slider, and n-type slot
5. Place the unloading components on a platform for collecting and unloading materials.
6. Behind the drive roller, there is a pressure shaft component consisting of a cylinder, pressure roller, drive motor, chain, and sprocket.
7. The translation part is equipped with a translation pushing mechanism, cylinder, linear track, and slider.
8. Inside the outer sheet metal cover of the electrical control, it is easy to transport, install and debug.
Process flow steps;
S0， The inflation shaft is placed at the spare bracket, with 1 # rod and 2 # roller, and the transmission friction material curled. The material receiving device clamps both ends of the main inflation shaft to prevent material friction, slippage, and jumping.
S1， The material winding reaches the set meter counting alarm, and the translation device pushes the prepared inflation shaft to the designated position. Then, the inflation shaft is fixed by the upper and lower grooves of the pressure shaft, and the cylinder controls the vertical movement. The inflation shaft is placed on the surface between the 3 # roller and the 4 # roller, and is transmitted by friction on the roller surface. When the sensor senses the friction transmission between the inflation shaft and the roller surface. The pressure roller starts to run at the set speed, acting as a resistance, while the cylinder works to push the pressure roller to press the material on the roller surface, and the cutting mechanism begins to operate. As the straight track is perpendicular to the 90 degree direction, the cylinder pushes the cutting tool to complete the cutting action
After S2 cutting is completed, the feeding cylinder pushes the coiled material to the unloading platform,
When the sensor detects that the material is being pushed to the discharge collection platform, the translation cylinder pushes the coiled material between operations 1 # and 2 #,
Rod 3 and roller 4 are in standby mode, while rollers 1 and 2 are in operational mode,
After the completion of the process above S4, the next cycle will cycle sequentially.
